Non-halogenated non-cross-linked axially arranged cable

Abstract

Axially arranged cable designs, such as coaxial and triaxial cable designs, utilizing non-halogenated and non-cross-linked construction materials (thermoplastics), particularly in a dielectric layer, and the methods of making the same.

1 . A cable comprising: 
 a conductor; and    a non-halogenated thermoplastic dielectric material; 
 wherein said cable has a thermal capacity of at least 100° C.  
   
     
     
         2 . The cable of  claim 1  further comprising a shield.  
     
     
         3 . The cable of  claim 2  wherein said cable is an axially arranged cable.  
     
     
         4 . The cable of  claim 3  wherein said cable is a coaxial cable.  
     
     
         5 . The cable of  claim 4  wherein said cable is an RG-type cable.  
     
     
         6 . The cable of  claim 1  wherein said dielectric material is extrudable.  
     
     
         7 . The cable of  claim 1  wherein said dielectric material is foamed.  
     
     
         8 . The cable of  claim 7  wherein such dielectric material comprises foamed polypropylene.  
     
     
         9 . The cable of  claim 1  further comprising a jacket.  
     
     
         10 . The cable of  claim 9  wherein said jacket is a polyolefin.  
     
     
         11 . The cable of  claim 9  wherein said jacket comprises a non-halogenated thermoplastic material.  
     
     
         12 . The cable of  claim 9  wherein said jacket comprises a non-halogenated thermoplastic vulcanizate (TPV).  
     
     
         13 . The cable of  claim 9  wherein said jacket comprises a flame-retardant material.  
     
     
         14 . The cable of  claim 1  wherein said cable is a substitute for at least one of: a PTFE RG-type cable, an FEP RG-type cable, and a PFA RG-type cable.  
     
     
         15 . A coaxial cable comprising: 
 a center conductor having a longitudinal axis;    a layer of foamed polypropylene surrounding said center conductor along said longitudinal axis;    a shield surrounding said layer of foamed polypropylene along said longitudinal axis; and    a flame-retardant polyolefin jacket surrounding said shield along said longitudinal axis.    
     
     
         16 . The cable of  claim 15  wherein said cable is an RG-type cable.  
     
     
         17 . An axially arranged cable comprising: 
 a conductor comprising metal and having a longitudinal axis;    a layer of a foamed thermoplastic surrounding said center conductor along said longitudinal axis;    a shield comprising metal and surrounding said layer of foamed thermoplastic along said longitudinal axis; and    a jacket comprising thermoplastic and surrounding said shield along said longitudinal axis.    
     
     
         18 . The cable of  claim 17  wherein said foamed thermoplastic comprises foamed polypropylene.  
     
     
         19 . The cable of  claim 17  wherein said jacket comprises polyolefin.  
     
     
         20 . The cable of  claim 17  wherein said jacket comprises a thermoplastic vulcanizate (TPV).
